Waterblasting Operations
5.2 SK3000 Routine Start Up/Shutdown
Before operating the SK3000, check the fluid lev -
els in all components on the skid unit and on the
tractor or Hog Tool. A thorough understanding
of the component systems and their operation is
essential to the proper operation the Stripe Hog
tractor or Hog Tool and the SK3000. This manual,
the manuals for the tractor or Hog Tools and the
associated manufacturers’ information is provided
to enhance your knowledge of the SK3000. Make
sure you have read them carefully and fully un-
derstand the operation of the units.
You should walk around the skid unit and visu-
ally inspect the high pressure hoses, hydraulic
hoses, vacuum hoses, and all waterblasting
system components for obvious signs of leaks,
wear and deterioration. Do not operate the unit
until all questionable components are repaired or
replaced.
Always check the Hog Head nozzles and
spray bars for wear and damage before each
shift. Refer to High Pressure Hoses and
Nozzles in Section 2.6 (Water Blast Systems)
for information on inspecting spray bars and
nozzles).
The pavement will be damaged immediately
if high pressure blasting is activated without
the tractor or Hog Tool moving. Always make
sure tractor or Hog Tool is moving before
supplying high pressure to the Hog Head
and spray bar.
Pre-start Inspection Check List:
1. Inspect all hoses for chaffing and signs of wear.
2. Check fuel levels and make sure you have
enough for the shift.
3. Check engine, skid systems and tractor fluid
levels. Refer to the tractor and engine operat -
ing manuals.
4. Check the fluid level in the tractor hydraulic
system.
5. Check all waterblasting and vacuum compo-
nents for oil leaks, damaged or loose bolts
and parts.
6. Inspect the Hog Head for loose components
and damage.
7. Check that all quick release pins on the lad-
ders and ramp are in place, secure and in good
condition.
8. Check vacuum canister for water and the
vacuum filter. Drain water or clean filter as
required.
9. Check the vacuum blower and UHP pump drive
belt tension and alignment.
10. Check clean water tank level and fill if neces -
sary.
11. Drain waste tank and check debris level.
Empty if necessary.
12. Walk around skid and visually check all com-
ponents and look for obvious problems.
Start UP Procedure
1. Unload the tractor.
2. Connect the pressure water and vacuum hoses
to the tractor and position it for operation.
3. Set the tractor parking brake, start the tractor
engine and set the throttle to idle.
4. Make sure all switches are in the “OFF” posi-
tion and speed dial is set at “0”.
5. Start the SK3000 engine.
6. Allow the engine to warm up at idle speed for
several minutes.
7. Make sure the charge water pressure is above
30 PSI (2.1 Bar.)
8. Engage manual PTO on SK3000.
At this stage the following implements will
function:
A. Operation of charge water Pump.
B. Operation of the UHP Pump.
C. Operation of Vacuum System.
9. With the operator on the tractor, all personnel
clear and the Hog Head in the “UP” position,
turn the 40K PSI switch “ON”.
10. Set the SK3000 engine RPM to the desired
level for correct operating pressure setting
(800 RPM minimum - 2200 RPM max.) There
may be some variation of this depending on
the blasting equipment attached and/or the
manual bypass valve setting. The RPM of
the vacuum system is set in conjunction
with the 40K PSI pump RPM.
11. Check the nozzle spray pattern and the spray
bar weep holes for leaks.
